General Description
The LM4050/LM4051 are precision two-terminal, shunt-
mode, bandgap voltage references available in fixed
reverse breakdown voltages of 1.225V, 2.048V, 2.500V,
3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-critical
applications, the LM4050/LM4051 are offered in the sub
miniature 3-pin SC70 surface-mount packages (1.8mm
x 1.8mm), 50% smaller than comparable devices in
SOT23 surface-mount package (SOT23 versions are also
avail able).
Laser-trimmed resistors ensure excellent initial accuracy.
With a 50ppm/°C temperature coefficient, these devices
are offered in three grades of initial accuracy ranging from
0.1% to 0.5%. The LM4050/LM4051 have a 60µA to 15mA
shunt-current capability with low dynamic impedance,
ensuring stable reverse breakdown voltage accuracy over
a wide range of operating temperatures and currents. The
LM4050/LM4051 do not require an external stabilizing
capacitor while ensuring stability with any capacitive loads.
The LM4050/LM4051 specifications are guaranteed over
the temperature range of -40°C to +125°C.
